Popis: In this study, we investigated the effects of nonlinear behavior of the dimensionless concentrations of ester, ether, acid, alcohol and water in HiGee stripping under the three phases of reaction viz. catalyzed phase, liquid phase and gas phase. The mathematical model has been developed based on the nonlinear reaction diffusion equations (Rangaiah et al. Chem Eng Sci 80:242–252, 2012). The developed second order governing differential equations represents catalyzed phase is solved analytically and numerically using modified Adomain decomposition method and Finite element method using MATLAB program respectively. We have observed the good accuracy of the present results by comparing with the numerical solution and with published work (Rangaiah et al. Chem Eng Sci 80:242–252, 2012) in literature. Also, we have derived the analytical solutions for liquid and gas phases using Homotopy perturbation method. In addition, we have presented the analytical expression for effectiveness factor for all the concentration under the diffusion restrictions. The analytical expressions derived. There are good enough to predict the behavior of the system. The influence of dimensionless governing parameters is discussed and presented in graphically.
